MOTIVE POWER lFOR OPERATING SYSTEMS OFPUMPS.

SPECIFICATION forming part of Letters Patent No. 715,614, dated December9, 1902.

Application led March 11,1902. Serial No. 97,745. (N o model.)

To LZZ whom, it may concern: Y

Be it knownthat I, DANIEL D. SHAW, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements in Motive Power forOperating a System of Pumps; and I do hereby declare the following to bea full, clear, and exact d escription of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The present invention consists in an improvement in motive mechanism foroperating a system of pumps, the object being to provide Ya device ofthe class stated which shall be possessed of great capacity and capableof forcing water to any desired height for irrigation or other purposes,the pumping mechanism being comparatively simple in construction,economical in cost, reliable, durable, and efcient in use.

It consists in a pump-operating mechanism comprising a series of leversconnected with the pumps to be operated, a series'of actuating-leversconnected with said pump-levers, springs for moving the' saidactuating-levers in one direction, a frame carrying a series of wheelsor rollers for connecting said levers 4and moving them against theaction of said spring, and means for rotating said frame carrying thewheels, whereby they' 'will be caused to engage and operate the leverssuccessively.

It also consists in certain other novel constructions, combinations, andarrangements of parts, as will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure l represents a side elevation of apump-opererating mechanism constructed in accordance with the presentinvention. Fig. 2 is a top plan view of the same, a portion of the framebeing broken away to reveal some of the gear of the device. Fig. 3 isatop plan view of a portion of the machine-frame, showing the rollers orwheels 'and the frame or wheel which carries the same. Fig. f1 is ahorizontal sectional view through the frame of the machine, showingthe'levers connected with the pumps. Figs. 5 and 6 are detailedsectional views showing the mounting of the acfor operating a series ofvpumps so arranged that some or all of them may be operatedvsimultaneously or successively, as' may be found desirable. A number ofpumps can be employed; but for the-sake of illustration I have shown inthe drawings six pumps 4, preferably grouped about a central air-chamberand outlet-pipe 12. Each of the pumps is supported on a base or door, as3, and is connected with the air-chamber 12 by pipes 11. The air-chamberl2 may be formed in any suitable manner, having an outlet at its lowerend, connected with the discharge-pipe 13. f Mounted upon a platform 3,in suitable proximity to pumps 4, are standards 5a, which rise,preferably, above the upper ends of the pumps and are bifurcated attheir upper ends to receive pump-operating levers 5, one lever beingprovided for each pump. The levers 5 extend toward the pumps at theirinner ends and are pivotally connected with the piston-rods of thepumps, while the outer ends of the said levers are connected with theupper portion of the machine-frame 9 by means of springs 7, whichnormally tend to draw the outer ends of the said levers upwardly,thereby effecting continuing movement to the pump-pistons. The door 3,as well as the upper portion of the frame 9, is

supported upon a series of posts or standards 10 l0, arranged about themachine. Pivoted at a suitable point with respect to the pumps, as at9a, are a series of actuating-levers 8, which are connected, by means ofrods 6, with the levers 5. Each of the rods 6 pivotally engages a lever5 at 6a and connects the same with its corresponding operating-lever 8,being pivotally joined to the latter at 8. Op- @rating-levers 8a may bepivoted to the frame 9 in any suitable or desired manner; but I preferto form the said leverswith a curved or hooked end portion which isfulcrumed, as shown in Figs. l, 5, and 6. 'Ihis curved portion in thelevers permits the same to be piv- 'oted on the outside of the frame 9,and yet allows its outer end to be passed upwardly through an aperturein the said frame to lie in a recess 40, formed in the upper surface ortop of the frame 9. The greater portion of the lever 8 is made in theform of a broad flat bar, which when resting in the recess is flush withthe upper surface of the frame 9. These levers normally are raised outof the recess 40 by the action of the spring 7. Running upon the top ofthe frame 9 are a series of flange-wheels 34, which are connected by aseparate and well-established frame 35, preferably formed more or lessopen and having a ring at its periphery, and connectingarms 36, forminga central spider at the oenter, as will be understood by reference toFig. 3. Upon the ring of this frame 35 are journaled smaller rollersorwheels 38 and 39, the rollers 39 being quite small and the rollers 38being of an intermediate size with relation to the rollers 34 and 39.The rollers or wheels are preferably arranged in groups, each groupcontaining one large roller 34, one intermediate roller 38, and onesmall roller 39. The rollers or Wheels 38 and 39 are so arranged uponthe frame 35 that they do not rest upon the frame9; but their outeredges are arranged in a plane with the upper edges of the rollers orwheels 34, so that the large gear-wheel 21, rest- Y ing upon the rollers34, will also rest upon each of the rollers 38 and 39. The gear-wheel 21is held in position by the flanges of the Wheels 34 and rests movablyupon all of the wheels or said rollers. The gear-wheel 21is connected byone or more gears or pinions, as 23 and 24, which are secured tovertical shafts 25 and 26, extending to a point near the base of themachine. Each ofthe shafts 25 and 26 carries beveled gears, as 27 and28, which mesh with corresponding beveled gears 29 and 30, carried by ahorizontally-driven shaft 31. The shaft 31 finds suitable bearings injournalboxes 32 and 33,' arranged on the base of the machine. The shaft3l may be driven by any suitable power, (not shown,) and through theshafts 25 and 26 and the pinions 23 and 24 movement may be imparted tothe gearwheel 21. The gear-wheel 2l is preferably forced against theperipheries of the Wheels 34, 38, and 39 by means of a series of rollers20 20, carried by a frame 18 and arranged above the gear-wheel 21. Thesaid frame 18 is formed at suitable intervals with rigidlyextendingprojections 17 17, which surround and move upon vertical standards 1616, rising from the frame 9 just outside of the periphery of thegear-wheel 21. The upper ends of the standards 16 are provided withadjusting ends 37, between which and the upper surface of the frame 18are interposed coiled springs 41, so that the frame 18 and the rollers2O are forced with yielding pressure normally against the upper surfaceof the gearwheel 21. Projections are also formed on the said frame 18,which receive the upper ends of the shafts 25 and 26, holding them inproper position. By means of the frame 18 and the springs 41 thegear-wheel 21 will be held in such position as to cause the rollers 34,38, and 39 to engage in succession and depress the operating-levers 8 asthe said gear-wheel 21 is rotated by means of the gearing abovedescribed.

In operating the device power is applied to the shaft 31, which in turnimparts motion to the gear-wheel 21 through the shafts 25 and 26 andpinions 23 and 24. As the gear-wheel 21 is rotated the rollers or wheels39 will first come into engagement with the upwardlyprojecting end ofthe lever 8. As the movement of the gear 21 and the wheel beneath itcontinues the wheel 38 will next `engage the levers 8 and force themdown still more, and nally the wheels 34 will roll upon the fiatportions of the levers 8, depressing them to their fullest extent andbringing their outer ends flush with the surface of the frame 9. Thearrangement of the wheels with respect to the levers 8 may be such thatall the levers are depressed at one time; but, preferably, they arearranged so as to successively depress the levers, as indicated inFig. 1. Thus some of the pumps are always forcing liquid, while thepistons of the other pumps are returning in their strokes for furtherpumping action. Some of the pumps will thus always be feeding liquid inthe air-chamber 12, which in turn will deliver it through thedischargepipe 13 to any desirable point. It will thus be seen that in avery simple and economical way a series of pumps can be employed bycontinuous application of power and that a continuous flow of liquids ofany desired power may be obtained.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. A pump mechanism, comprising a series of pumps, an air-chamberadapted to receive the flow of liquid through each pump, pumpleversconnected with the pumps for operating the same, actuating-leverspivoted on the frame above the pump-levers and connected therewith, thesaid actuating-levers having curved end portions whereby they may bepivoted outside the same, and yet have their inner ends extend throughapertures in the frame and capable of engaging depressions in the top ofthe said frame so as to lie flush with its upper surface, and a seriesof wheels for depressing the said levers and thereby operating thepumps, substantially as described.

2. In a pump mechanism, the combination with a suitable frame, of a pumpwithin the same, an air-chamber adapted to receive a flow of liquidthrough said pump, a pumplever connected with the pump for operating thesame, an actuating-lever pivoted on the same above the pump-lever, andconnected therewith, the said actuating-lever having a curved andslightly laterally-disposed end portion pivoted outside the frame, theinner end of said actuating-lever extending through IOO No. 7|5,'6|5.Patented nec. 9, |902.
